From the Wiki for the 1970 Funkadelic album Free Your Mind... And Your Ass Will Follow (which, in itself, is a great name for an album):
"The album and its title track, a feedback-drenched number taking a third of the album's length, introduces the subversion of Christian themes explored on later songs, describing a mystical approach to salvation in which 'the Kingdom of Heaven is within' and achievable through freeing one's mind, after which one's ass will follow."
Speechless. I can't stop laughing about this. More in a couple of days, when I actually sit down and listen to a lot of this.
